MIXER.

To all whom it may concern: Y

Be it known that I, J 0B IRA CHAMBERS, a citizen of the United States, residing at Eddy, in the county-of Kay and State of Oklahoma, have invented a new and useful Mixer, of which the following is a specification.

-Tbis invention hasreference to improvements in mixers to be introduced in the con-l duitleadin sion engine or encrines, and its object is to incorporation of a hydro-carbon fluid:` with the air it enriches after the hydro-carbon hasl been `mixed with the air in the carbureter.

In the device wherein a liquid hydro-carbon, such as lgasolene, is intermixed with air, and which device is commonly known as a carbureter, it frequently, transpires that the intermixtnre is not complete and the liquid hydro-carbon is not always thoroughly volatilized, so that there is a wastage of the fuel, of which -gasolene may 'be taken as typical, due vto the imperfect mixture.

The present invention comprises ascreen of tine mesh gauze of substantially conical foruiwith the apex of the cone directed toward the carbureter and the base of the cone away from the carburetor, and this device which is designed to provide a homogeneous mixture of the hydro-carbon andthe air is placed in the manifold leading to the engine or engines, which mixer may be constructed in sizes to tit. in intakevmanifolds.

The invention will be best understood from a consideration of the following de-v tailed description taken in`connection with the accompanying drawings forming a part of this specification, With the understanding, however, that while the structure shown in the drawings is a practical form of the invention it 'may assume other forms With- .out departing from the salie'nt;features of the invention.

In the draw1ngs:-F1gure 1 v1s an elevation wlth parts 1n section showing a`;car

Referring to the drawings, there is shown a carbure'ter l, which may be 4taken as typical of any suitable carbureter for the struclSpeeitcation of Letters Patent. Application tiled March 25, 1911. Serial No. 616,942.

ture of the carbureter is' not material to the present invention. From this carbureter there leads a pipe 2 terminating in a flange 3 matching a like flange 4 on the correspondingend of a manifold 5, such as is commonly .employed for conducting ythe charge to the engine or engines, but the par# ticular structure of the several parts already described is not material to the present in'- vention and may follow the usual practice.

The hydro-carbon most commonly .em-

ployed in producingr the admixture with I air to form the explosive charges for the -engine is gasolene', and such gasolene is,

usually sprayed into an air stream and the mixture is ultimately carried to the eXplosion' chamber ofthe engine. For best results the liquid gasolene sh'ould be entirely volatilized and absorbed by the air,'so that. the air may become enriched to the requisite degree, and the admixture should be very intimate.

lt is the purpose of the present invention to cause'the thorough incorporation of the hydroearbon with the air and for. this purpose there is provided a thimble 6 preferably of truste-conicalform with a radial flange 7 at `the hase end, the diameter of such base end being such that the flange 7 may he introduced between the flanges 3 and 4 to be clamped thereto by bolts 8 usually employed to couple the conduit 2 to the manifold 5, these bolts traversing the flanges 3 a nd 4, while the radial extent of the flange 7 may be such as to not interfere -With the bolts 8, but at the same time form a suiliciently tight connection to prevent leakage.

Secured tothe small end of -the thimble 6 is a gauze cone 9, the apexof which is presented toward the base end of the thimble G, while the base end of the ,cone 9 1s united atits edges to the smaller end of the thimble 6, thisunion being brought about by 4 l soldering or otherwise. For best results the walls of the cone 9 should have an angle of about thirty-five degrees, although small variations from this angle will not. prevent satisfactory operation ofthe device.

.The stream of air and gasolene Vapor coming from the carbureter l must pass through theI gauze cone 9, the apex of which is presented t0 suoli-oncoming stream so that the latter will pass along the outer surface of the cone 9 from the apex toward the base thereof and will find its Way into the interior of the cone, and sointo the manifold 5 through the multitude of inter-V stices between the interlaced strands forming the cone 9. By this means theoncoming stream meets a constantly increasing surface of gauze and the stream is subdivided into a multitude of ne streamsI in the passage through the gauze, the presentation of the apex of the gauze cone toward the oncoming stream greatly facilitating the action and rendering it much more certain and eilicient than would be the case were the on-coming stream to pass first to the interior of the cone and through the same to the exterior thereof. The act-ion of the gauze cone 9 is to cause a most thorough intermixture which in practice has been found to be far more intimate than when the cone is omitted, and, furthermore, the cone ca uses a change in the direction of travel ,of the stream of air and hydro-carbon Huid whence such stream is highly sub,- divided, so that these minute streams are broughtinto interfering relation one to the other in steh manner that any portions of the stream where the air and hydro-carbon Huid are not thoroughly intcrmixed become thoroughly intermixed. The taper form of u the thimble also contributes to the eiiicicnt action of the gauze cone b' brinein thc 'stream more rapidly into engagement ,with

the walls of the cone than would be the case were he thiinble cylindrical or of expand ing forni.

lt is essential for the best results that. the

' interniixture of the hydro-carbon fluid with the air should be homogeneous, butthis does not occur with carbureters as usually employed in connection with explosion en gincs, but with the present iiirention this is brought about by the sub-dividing and direction changing action of the gauze upon ,the oil-coming Huid stream, whereby the mixtureis made more thorough than otherwise-bv'thc intel-mingling of the many tine streams, so that separate streams of air or gasolene vapor, as the case may be, are broken up and caused to intel-mingle instead of maintaining such separate relation until vthe explosion chamber of the engine is `reache. l

Actual experience hasddeino'nstrated that `from eighteen to twenty-three per cent. of thc gasolene before 'required is saved because of the improved mixture, the efficiency of the charge being thereby so increased that' less fuel is required for the development of the necessary power than is the case where the incorporation of the gasolene in the air stream is less thorough and the approach to a homogeneous mixture less ].nonounced.

The thimble with the gauze sleeve is readily introducible into the manifold where joined by the conduit coming fioiii the carbureter irrespective of the type. of carbuF i Because of the thorough internux reter. turc produced. the amount of fuel necessary to develop a certain power is reduced, excessive heating of the engine is prevented and .because of the homogeneous character of the mixture the deposition of carbon in the tiring or explosion chamber is prevented and spark-plug troubles are correspondingly reduced. l What. is claimed is An auxiliary mixing device for carbureters for introduction in the charge conveying conduit leading from the carburetei Ato the point ofutilizat-ion, comprising an 'open ended tliiinble of frusto-coiiical forni with a radial flange at the larger end for S'Clll'llg th@ thmble in the conduit, and a gauze cone secured at its largel or basic end to the smaller end of thethinihle andvhaving its apex directed toward thc larger end of-the thimble, the apex end ofthe gauze .i

cone being directed toward the carburetor when the device is installed in the charge conveying conduit.

ln testimony, that 1 claim the foregoing as my own, I have hereto affixed my ,signin ture inthe presence of two witnesses.
